Two brown pelicans and a flock of seagulls rest on the shore of Ship Island as a boom line floats just offshore Thursday, April 29, 2010 in Gulfport, Miss. Several hundred yards of boom line has been set up on the north side of the island to try and contain the oncoming oil spill. Crews are placing the boom in different areas on Coast waterways to help protect against an approaching oil slick in the Gulf of Mexico. (AP Photo/The Sun Herald, William Colgin)
